ANZESTHETICDI$IY?EN$ING CONTAINER,

Application filed January 25, 1922. Serial No. 53l,650.

To all whom it may concern:

Be it snown that l, CARLOS W. Jones, a citizen of the United States,residing at Kansas C ty, in the county of Jackson and State of?llclissouri, have invented certain new and useful Improvements inAntesthetic-Dispensingg C(mtaincrs: and I do declare the iolloun ing' tobe a full, clear, and exactdescription ot the invention, such as willenable Others skilled in the art to which it appertains to make and usethe same. reference being had to the accompanying drawings, and to thefigures oi reference inarlred thereon, which torn'i a part of thisspecification.

lhis invention relates to a dispensing container, the discharge of whichis provided with a dropper having a controlling valve tor determiningthe rate of discharge of the contents of the container, the valve beingadapted to be manipulated so that the disch... e orifice can be closed,thereby permitting "fractional. discharge of the contents of thecontainer at infrequent intervals without materially affecting thecondition of the contents.

For example, theinvention is particularly applicable for use byanaLsthetists in administering anzesthetics, for example, other, topatients as the dispensing; container can be caused to discharge at anygiven rateunder the control of the anaesthetist.

llther usually is put up in metal containers with discharge tubes attheir ends, the discharge tubes preferably consisting-of so'li't metalwhich may be easily ruptured or pierced to make the orifices throughwhich the discharge may take place.

In practice it is diilicult to control the rate of dischargeand unlessone is quite expert, there isalways danger of over-saturating the maskwith manifold disadvantages and great danger to the patient It too muchother is dropper upon the mask, paralysis of the respiratory organs isliable to occur and this is more or less truein a great number of caseswhere ether is administered According to my invention, the rate ofdischarge can be digitally controlled'by the anaesthetist, thereceptacle being held in the hand and the dropper-controlling elementmanipulated between the thumb and the index finger.

There is another very important feature of my invention in that thecontainer may be sealed oil after each discharge As above explained, thecans nowin use are provided with soft discharge orifices or tubes andthe most popular cont liner is a four ounce can. In administering theother it frequently happens that a comparz tively small fraction of theentire contents of the can is required. It the can is kept with theremainiiro contents for any appreciable time. the contents of the canwill deteriorate andif nsed, will apparently set up toxins in thesystem, which cause qreat distress to the patient, such as nausea, painsand the like.

it is one of the purposes of my invention to maintain as nearly aspractical a uniform quality of the ether over a considerable period ofuse, that 'is, whereas, with the ordinary contaii the most volatile constituents pass oft" shortly after the can is opened. accowlinn to myinvention, a considerableportion of these at least can be retained inthe can because as soon as the first application of the other has beencompleted, the discharge orifice will be sealed oft so that liability ofdeterioration of the other due to oxidation or from any other causeswill. be reduced to a minimum, it not wholly avoided.

Therefore, I may manipulate the dropper to cause the discharge orificeto open to varying degrees to vary the effective port area 01 thedischare'e opening; and therebycontrol the rate of discharge of thecontents otthe can and then quickly seal oil the discharge orifice sothat the contents of the can will 3e as nearly as practicable in itsoriginal condition. 1, thereby, avoid the liability oi the more volatilegases escaping to atmosphere and leaving; only a poisonous residue inthecan. i

The advantages above recited will. be clearly apparent to, physicians,surgeons, annesthet-ists and the like.

In order to convey a proper conception ofmy invention, I haveillustrated one form of the device in the accompanying drawings, inwhich Fig. 1 is a perspective view of a dispensing container constructedin accordance with my invention.

Fig. 2 is a fragmentary side View of the container, parts being brokenaway to show till the dispensing stopper or dropper in longitudinalsection.

Fig. 3 is a disassociated View of the dropper controller and the droppertube, parts of each being shown in section, and

l is a bottom end view of the controller. showing the valve carriedthereby.

The receptacle 1 may partake of any ap propriate form but it ispreterably cylindrical with a plug 2 to close an orifice 3 at one endthereof. The orifice 3 is the filling orifice and when the receptacle isfilled, the plug may be secured in place by a spanner wrench or anysuitable tool and for this purpose I preferably cast two lugs i and 5 onthe plug, as clearly seen in Figs. 1 and 2.

The term of plug and orifice, however. constitute no partof myinvention.

The invention resides rather in the broad conception of providing avariable dropper which is a part. of the receptacle and which has avariable effective port area to control the rate of discharge.

In Fig. 2 it will be seen that the dropper consists of a tube 6. one endof which extends within the receptacle and the other end with out thereceptacle. The inner end is closed. preferably by aplug 'z' havingthrough port or orifice 8 longitudinally thereof to comn'iunicate withthe forward portion of the tube 6. The plug 7 is shown as having a valveseat 9 to receive a valve carried by the. controller. The controller isshown as a threaded stem 10, the exterior threads of which engage theinterior threads 11 of the tube 6 so that the stem may be adjustedlongitudinally of the tube to move the valve 12 and from the seat 9. Thelongitudinal bore or port 13 in the stem is open to atmosphere. as at 11:. The other end terminates in a plurality of radial ports 15, aboutthe valve 12 and communicating with a space 16 between the valve and theskirt portion 17 of the stem 10. The outer end of the stem 10 isprovided with a flange or cap portion 18 the exterior or which isknurled as at 19 so that it may be easily grasped between the indexfinger and the thumb to manipulate the stem when the can or container isheld by the anaesthetist.

lVlien the parts are pro )erly assembled and it is desired to dischargesome of the contents from the can, the cap or knurled portion 19 may bedigitally manipulated to unscrew the stem enough to unseat the valve 12from the seat 9. The contents of the can may then pass through theorifice 8 into the space 16 surrounding the valve 12, through the ports15, through port 1-3 and discharge from the end 14.

The first disel arge will. indicate whether or not the etl ective portarea is less or more than desired and since the stem or dropper memberis under direct control of the lingers, the knurled portion 19 may beturned in ither direction to control the ell'ective port.

area so as to absolutely control the rate of discharge. llheretore,liability of flooding .11 the mask or excessive discharge will beentirely eliminated.

Futhermore, when the proper amount of anaesthesia has beenachninistered, the anaesthetist may turn the knurled portion 15) toscrew the stem witl in the tube (5 so to seat the valve 2 and as thiscan be quickly done liability of the highly volatile con stituents ofthe contents of the receptacle escaping or evaporating will be entirelyeliminated.

I am aware that droppers have been used before and that valves havebeeen provided in containers to vary the effective port areas andthereby the rate of discharge. but so far as I know I am the first toprovide an anaesthesia-dispensing receptacle in which the rate ofdischarge can be positively controlled and in which the controllingmeans may be used to seal oif the discharge orifice of the receptacle.

Vlhat I claim and desire to secure by Letters Patent is: i

A dispensing receptacle for administering anaesthetics comprising acontainen an interiorly threaded tube carried by an er:- tending througha wall of the container, a plug threaded into and closing the inner endof the tube, said plug having a central, through port, a frustro-conicalinner face, shouldered with respect to the walls of the plug to form anannulus within the tube and having a valve seat opening to the throughport, and a stem threaded into the outer end of the tube, havingachambered inner end forming a valve for cooperation with said valveseat and a skirt surrounding the frustro-conical portion of said plug,said stem having a port opening through its outer end and terminatingshort of its inner end and having a plurality of ports radiating fromthe inner end of said main port and opening through the stem at the baseof the valve, the outer end of the stem having a handle portionsurrounding the outer end of the tube.

In testimony whereof I atfix my signature.

CARLOS W. JONES.
